Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and more specifically, relates to an arch support trolley. Background Art

[0002] In recent years, as China has accelerated the construction of the national comprehensive transportation network, the focus of the highway network has gradually shifted from the eastern coastal areas to the central and western regions. Mountain tunnels have emerged in large numbers on highways. During tunnel construction, in order to prevent the surrounding rock from being poor and unstable, resulting in excessive deformation or collapse, during the construction process, it is necessary to install an arch support and form a rigid body with anchor bolts, steel mesh, connecting steel bars, concrete, etc. to support and maintain the stability of the tunnel.

[0003] However, the installation of the arch support and its support operations include various tasks such as setting up the arch support, installing anchor bolts, welding tie bars, and hanging mesh. All along, the main method has been the manual bench, and through the construction method of manual pulling and carrying, a large number of personnel are invested, the labor intensity is high, the safety is poor, and the automation degree is low.

[0004] Especially after the promulgation of the "Nine Articles on Tunnel Construction Safety", it is required to strictly control the number of workers, and the working face requires mechanization, etc. The level of "standardization, mechanization, specialization, and informatization" in tunnel construction needs to be improved urgently. Improving the safety efficiency of tunnel construction and replacing people with tunnel construction machinery are also the future development trends.

[0005] However, for the existing arch support trolley, when performing boom lifting and swing adjustment, in order to ensure the adjustment accuracy and construction safety and avoid interference and collision during the adjustment of the boom, the operation process is relatively cumbersome, resulting in low construction efficiency. Summary of the Utility Model

[0006] Aiming at the problem that the operation process of the existing arch support trolley is relatively cumbersome when performing boom lifting and swing adjustment, resulting in low construction efficiency, the purpose of the utility model is to provide an arch support trolley, which includes: a trolley body; an upper boom, movably arranged on the trolley body, capable of lifting up and down and swinging left and right relative to the trolley body; a lower boom, movably arranged on the trolley body, capable of lifting up and down and swinging left and right relative to the trolley body; wherein, the lower boom can swing left and right under the upper boom to realize the construction of the arch support trolley.

[0007] It should be noted that for existing arch support trolleys, either the three boom structures are large in volume, heavy in mass, and high in cost, or the two booms arranged in parallel require the replacement of the left and right booms, which wastes time, results in a long construction time, and low construction efficiency. Compared with the existing two-boom arch support trolley, by arranging the two boom structures vertically offset to form an upper boom and a lower boom, the lower boom can shuttle left and right under the upper boom, so that the lower boom can be used as both the left boom and the right boom without the need to replace the left and right booms, thereby improving the construction efficiency of the two-boom arch support trolley and realizing the three-station construction of the two booms of the arch support trolley.

[0008] Further, the arch support trolley further includes: a boom lifting monitoring module coaxially arranged with the lifting shaft of the boom for monitoring the rotation angle of the lifting shaft of the boom; a boom swinging monitoring module coaxially arranged with the swinging shaft of the boom for monitoring the rotation angle of the swinging shaft of the boom.

[0009] It can be understood that by setting a boom lifting monitoring module coaxially arranged with the lifting shaft of the boom, the rotation direction and rotation angle of the lifting shaft of each boom can be accurately obtained; by setting a boom swinging monitoring module coaxially arranged with the swinging shaft of the boom, the rotation direction and rotation angle of the swinging shaft of each boom can be accurately obtained, so as to more accurately adjust the lifting and swinging of each boom, ensure the adjustment accuracy rate and construction safety, avoid interference and collision during the adjustment of the boom, and is relatively convenient to operate with high construction efficiency.

[0010] Further, the arch support trolley includes an upper boom and a lower boom, and the lower boom can swing left and right under the upper boom to realize the three-station construction of the two booms of the arch support trolley.

[0011] Further, the upper boom and the lower boom are arranged on the trolley body through a turntable seat, and the turntable seat includes: an upper boom mounting seat and a lower boom mounting seat, and the upper boom mounting seat and the lower boom mounting seat are arranged at intervals along the height direction of the turntable seat.

[0012] Further, the upper boom mounting seat and the lower boom mounting seat are arranged at intervals along the vehicle body direction of the trolley body.

[0013] It can be understood that arranging the upper boom mounting seat and the lower boom mounting seat at intervals along the vehicle body direction of the trolley body can make the upper boom and the lower boom arranged at intervals along the vehicle body direction of the trolley body, thereby further reducing the difficulty of adjusting the lifting and swinging of the upper boom and the lower boom and better avoiding interference and collision during the adjustment of the upper boom and the lower boom.

[0014] Further, the turntable seat is of a box-shaped structure.

[0015] It can be understood that, compared with a solid turntable base, by setting the turntable base as a box structure, the bending and torsion resistance of the turntable base can be improved, and the shock absorption performance of the turntable base can be enhanced, thereby ensuring the construction stability of the upper boom and the lower boom, guaranteeing construction safety, and improving construction efficiency.

[0016] Furthermore, the upper boom mounting seat is movably arranged on the turntable base; the turntable base further includes: a lifting mechanism, arranged below the upper boom mounting seat and drivingly connected to the upper boom mounting seat.

[0017] It can be understood that by arranging a lifting mechanism below the upper boom mounting seat and drivingly connected to the upper boom mounting seat, the upper boom mounting seat can be adjusted along the height direction of the turntable base through the lifting mechanism, so that the height difference between the upper boom mounting seat and the lower boom mounting seat can be flexibly adjusted according to actual construction requirements, further reducing the difficulty of lifting and swinging adjustment of the upper boom and the lower boom, and better avoiding interference and collision during the adjustment of the upper boom and the lower boom.

[0018] Furthermore, the lifting mechanism is arranged inside the box structure, and the lifting mechanism can drive the upper boom mounting seat to move downward along the height direction of the turntable base to accommodate the upper boom mounting seat inside the box structure.

[0019] Furthermore, a first manipulator is provided at the end of the upper boom of the arch trolley, and a second manipulator is provided at the end of the lower boom.

[0020] Furthermore, the arch trolley further includes: a first hanging basket, arranged on the upper boom; a second hanging basket, arranged on the lower boom; wherein, the first hanging basket is detachably arranged on the upper boom through the first manipulator.

[0021] It can be understood that by arranging the first hanging basket to be detachably arranged on the upper boom through the first manipulator, the first hanging basket can be flexibly disassembled and assembled according to actual construction requirements, improving the applicability of the arch trolley.

[0022] Furthermore, the second hanging basket includes a basic basket, a first extension basket and a second extension basket. The first extension basket is movably arranged on the basic basket and is used to expand the construction workstations of the hanging basket in the horizontal direction; the second extension basket is movably arranged on one side of the basic basket and is used to expand the construction workstations of the hanging basket in the vertical direction.

[0023] It can be understood that the second hanging basket can be expanded horizontally through the first expansion basket and vertically through the second expansion basket, so that one second hanging basket can have two working positions. Moreover, there is a distance in the width direction and a large drop in the height direction between the two working positions, and the two working positions do not interfere with each other during construction. Furthermore, it can enable the two-arm arch support trolley to achieve the effect of a three-arm and three-hanging basket working position, improving the construction efficiency of the two-arm arch support trolley.

[0024] Furthermore, the second manipulator is adjustably angled and arranged at the end of the lower boom; wherein, the second manipulator can be adjusted according to the construction position of the lower boom.

[0025] Furthermore, the number of the second manipulators is two; wherein, the corresponding second manipulator can be selected for grasping operation according to the construction position of the lower boom.

[0026] The technical effects and advantages of the present utility model:

[0027] 1. By providing a boom lifting monitoring module coaxial with the lifting shaft of the boom, the rotation direction and rotation angle of the lifting shaft of each boom can be accurately known; by providing a boom swing monitoring module coaxial with the swing shaft of the boom, the rotation direction and rotation angle of the swing shaft of each boom can be accurately known, so as to more accurately lift and swing-adjust each boom, ensure the adjustment accuracy rate and construction safety, avoid interference and collision during the adjustment of the boom, and the operation is relatively convenient with high construction efficiency.

[0028] 2. It should be noted that for the existing arch support trolleys, either the three-boom ones are large in volume, heavy in mass and high in cost, or the two parallel booms need to exchange the left and right booms, which wastes time, has a long construction time and low construction efficiency. Compared with the existing two-arm arch support trolleys, by arranging the two booms vertically offset in the form of an upper boom and a lower boom, the lower boom can shuttle left and right below the upper boom, so that the lower boom can be used as both the left arm and the right arm without the need to exchange the left and right booms. Furthermore, the construction efficiency of the two-arm arch support trolley can be improved, and the double-arm three-position construction of the arch support trolley can be realized.

Specific embodiments

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0041] See Figure 1 , which is a schematic structural view of an arch formwork trolley provided by the present invention. Combining Figures 1 to 8 , the arch formwork trolley 100 includes: a trolley body 10; at least two booms, movably arranged on the trolley body 10, capable of lifting up and down and swinging left and right relative to the trolley body 10; a boom lifting monitoring module 51, coaxially arranged with the lifting shaft of the boom, for monitoring the rotation angle of the lifting shaft of the boom; a boom swing monitoring module 52, coaxially arranged with the swing shaft of the boom, for monitoring the rotation angle of the swing shaft of the boom. For example, the boom lifting monitoring module 51 is a sensor coaxially arranged with the lifting shaft of the boom, and the boom swing monitoring module 52 is a sensor coaxially arranged with the swing shaft of the boom.

[0042] It can be understood that by setting the boom lifting monitoring module 51 coaxial with the lifting axis of the boom, the rotation direction and rotation angle of the lifting axis of each boom can be accurately obtained; by setting the boom swing monitoring module 52 coaxial with the swing axis of the boom, the rotation direction and rotation angle of the swing axis of each boom can be accurately obtained, so as to more accurately adjust the lifting and swinging of each boom, ensure the adjustment accuracy rate and construction safety, avoid interference and collision during the adjustment of the boom, and is relatively convenient to operate with high construction efficiency.

[0043] Furthermore, the arch formwork trolley 100 includes an upper boom 20 and a lower boom 30. The lower boom 30 can swing left and right below the upper boom 20 to realize the double-arm three-station construction of the arch formwork trolley 100.

[0044] It should be noted that for the existing arch formwork trolley 100, either the three booms are large in volume, heavy in mass and high in cost, or the two parallel booms need to exchange hands between the left and right arms, wasting time, having a long construction time and low construction efficiency. Compared with the existing two-arm arch formwork trolley 100, by arranging the two booms in an up-and-down staggered manner in the form of the upper boom 20 and the lower boom 30, the lower boom 30 can shuttle left and right below the upper boom 20, so that the lower boom 30 can be used as both the left arm and the right arm without the need to exchange hands between the left and right arms, thereby improving the construction efficiency of the two-arm arch formwork trolley 100 and realizing the double-arm three-station construction of the arch formwork trolley 100.

[0045] Furthermore, the upper boom 20 and the lower boom 30 are arranged on the trolley body 10 through a turntable seat 40. The turntable seat 40 includes: an upper boom mounting seat 41 and a lower boom mounting seat 42, and the upper boom 20 mounting seat and the lower boom 30 mounting seat are arranged at intervals along the height direction of the turntable seat 40.

[0046] Furthermore, the upper boom 20 mounting seat and the lower boom 30 mounting seat are arranged at intervals along the vehicle body direction of the trolley body 10.

[0047] It can be understood that arranging the upper boom mounting seat 41 and the lower boom mounting seat 42 at intervals along the vehicle body direction of the trolley body 10 can enable the upper boom 20 and the lower boom 30 to be arranged at intervals along the vehicle body direction of the trolley body 10, thereby further reducing the difficulty of adjusting the lifting and swinging of the upper boom 20 and the lower boom 30 and better avoiding interference and collision during the adjustment of the upper boom 20 and the lower boom 30.

[0048] Furthermore, the turntable seat 40 is of a box-type structure.

[0049] It can be understood that, compared with the solid turntable base 40, by setting the turntable base 40 as a box structure, the bending and torsion resistance of the turntable base 40 can be improved, and the shock absorption performance of the turntable base 40 can be enhanced, thereby ensuring the construction stability of the upper boom 20 and the lower boom 30, guaranteeing construction safety, and improving construction efficiency.

[0050] Furthermore, the mounting seat of the upper boom 20 is arranged on the turntable base 40 in a liftable manner; the turntable base 40 further includes: a lifting mechanism 43, which is arranged below the mounting seat 41 of the upper boom and is drivingly connected to the mounting seat of the upper boom 20.

[0051] It can be understood that by arranging a lifting mechanism 43 drivingly connected to the mounting seat of the upper boom 20 below the mounting seat of the upper boom 20, the mounting seat of the upper boom 20 can be adjusted along the height direction of the turntable base 40 through the lifting mechanism 43, so that the height difference between the mounting seat of the upper boom 20 and the mounting seat of the lower boom 30 can be flexibly adjusted according to actual construction requirements, further reducing the difficulty of lifting and swinging adjustment of the upper boom 20 and the lower boom 30, and better avoiding interference and collision between the upper boom 20 and the lower boom 30 during the adjustment process.

[0052] Furthermore, the lifting mechanism 43 is arranged inside the box structure, and the lifting mechanism 43 can drive the mounting seat of the upper boom 20 to move downward along the height direction of the turntable base 40, so as to accommodate the mounting seat of the upper boom 20 inside the box structure, making the upper end surfaces of the mounting seat of the upper boom 20 and the mounting seat of the lower boom 30 flush, thereby being able to reduce the volume of the turntable base 40 in the non-construction state.

[0053] Furthermore, a first manipulator 21 is provided at the end of the upper boom 20 of the arch trolley 100, and a second manipulator 31 is provided at the end of the lower boom 30. For example, the tunnel arch includes an intermediate arch section and two edge arch sections arranged on both sides of the intermediate arch section; during the tunnel arch construction operation, the arch trolley 100 grabs the intermediate arch section through the first manipulator 21 at the end of the upper boom 20, and grabs the edge arch section through the second manipulator 31 at the end of the lower boom 30.

[0054] Furthermore, the arch trolley 100 further includes: a first hanging basket 60, which is arranged on the upper boom 20; a second hanging basket 70, which is arranged on the lower boom 30; wherein, the first hanging basket 60 is detachably arranged on the upper boom 20 through the first manipulator 21.

[0055] For example, during the construction in a small space such as a three-step excavation, the first hanging basket 60 arranged at the first manipulator 21 can be disassembled and then the construction operation can be carried out, so as to reduce the volume of the arch trolley 100 and ensure that the arch trolley 100 can also operate normally in a small space.

[0056] Further, the second hanging basket includes a basic basket, a first extended basket and a second extended basket. The first extended basket is movably arranged on the basic basket and is used to expand the construction workstations of the hanging basket in the horizontal direction; the second extended basket is arranged on one side of the basic basket in a liftable manner and is used to expand the construction workstations of the hanging basket in the vertical direction.

[0057] It can be understood that the second hanging basket can be expanded in the horizontal direction through the first extended basket and can also be expanded in the height direction through the second extended basket, so that one second hanging basket can have two workstations. Moreover, there is a distance in the width direction and a large drop in the height direction between the two workstations, and the two workstations do not interfere with each other during construction. Furthermore, the two-arm arch trolley 100 can achieve the effect of a three-arm and three-hanging-basket workstation, thereby improving the construction efficiency of the two-arm arch trolley 100.

[0058] Further, the second manipulator 31 is arranged at the end of the lower boom 30 in an angle-adjustable manner; wherein, the second manipulator 31 can be adjusted according to the construction position of the lower boom 30.

[0059] For example, when the lower boom 30 acts as the left arm for construction operations, the second manipulator 31 is in the first construction position to perform the grasping operation on the left tunnel arch segment; when the lower boom 30 swings from the left side to the right side under the upper boom 20, the lower boom 30 acts as the right arm for construction operations, and the second manipulator 31 can be adjusted from the first construction position to the second construction position to perform the grasping operation on the right tunnel arch segment.

[0060] Further, the number of the second manipulators 31 is two; wherein, the corresponding second manipulator 31 can be selected according to the construction position of the lower boom 30 for the grasping operation.

[0061] For example, one of the two second manipulators 31 at the end of the lower boom 30 is used to perform the grasping operation on the right tunnel arch segment, and the other is used to perform the grasping operation on the left tunnel arch segment. When the lower boom 30 acts as the left arm for construction operations, one of the second manipulators 31 is used to perform the grasping operation on the left tunnel arch segment; when the lower boom 30 acts as the right arm for construction operations, one of the second manipulators 31 is used to perform the grasping operation on the right tunnel arch segment.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0063] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments.
